The essence of last night's episode was about underestimating people and revenge. The Daenerys ending was fantastic. And I intend to find that music. But the Varys/Tyrion scene as well as the Tywin/Cersei scene were both enjoyable.

Say what you will about Tywin, but if it's about to get dangerous, I want him on my team.

"When the snows fall and the white winds blow, the lone wolf dies but the pack survives."
Winter is Coming

Now this is the Law of the Jungle—as old and as true as the sky; And the wolf that shall keep it may prosper, but the wolf that shall break it must die.
As the creeper that girdles the tree-trunk, the Law runneth forward and back; For the strength of the Pack is the Wolf, and the strength of the Wolf is the Pack.
